Sanyo Pancake Stepper Motor with Encoder: Bipolar, 200 Steps/Rev, 42×31.5mm, 5.4V, 1 A/Phase, 4000 CPR

This NEMA 17-size pancake bipolar stepping motor from Sanyo features an integrated high-resolution (1000 P/R) quadrature encoder that allows for 4000 counts per revolution of the output shaft when counting both edges of both channels. The stepper motor itself has a 1.8° step angle (200 steps/revolution) and each phase draws 1 A at 5.4 V, allowing for a holding torque of 1.9 kg-cm (26 oz-in).
